E

:
Produce as an invariable result. A puff of air on the eye elicits an eye blink.
:
The term elicit refers to reflexes where the unconditioned response bears a one-to-one relationship to the unconditioned stimulus. Because the unconditioned stimulus determines both the form and occurrence of the unconditioned response, we speak of the unconditioned response as being elicited rather than emitted as in the case of the operant.
:
The reliable production of a response by a stimulus in unconditioned or conditioned reflexes. Cf. RESPONDENT BEHAVIOR.
:
Respondent (CR) or reflexive (UR) behavior is said to be elicited in the sense that it is forced by the presentation of a stimulus (CS or US).
:
Conditional stimulus control that emerges as a by-product of other stimulus-control relations rather than through differential reinforcement. For example, if arbitrary matching has been arranged for pairs AB and BC (where the first letter of each pair corresponds to the sample and the second to the matching comparison) and testing shows that the transitive relation AC now also exists, then this relation is said to L.-e emergent. CE EQUIVALENCE CLASS.
:
The occurrence of operant behavior. A response that occurs without an eliciting stimulus is said to be emitted. The term applies to responding occasioned by a discriminative stimulus as well as to undiscriminated responding. Cf. OPERANT BEHAVIOR.
:
Produce, but not as an invariable result of any particular stimulus. A student in a class emits many responses which are not an automatic response to any preceding stimuli.
:
A term that describes the occurrence of operant behavior. In this text, familiar verbs such as express, perform, respond, and behave are used as equivalents. See also Operant behavior. 9
:
Operant behavior is said to be emitted in the sense that it occurs at some probability in the presence of a discriminative stimulus, but the SD does not force its occurrence.
:
Emotion is a state of the organism in which the form and frequency of several items of behavior in the ongoing operant repertoire are altered. The term emotion, as it is classically used, has the disadvantage of referring to an inner state which usually cannot be observed. The term emotional stimulus overcomes some of these difficulties because it describes a stimulus which alters many ongoing performances in the organism's repertoire other than those directly affected by reinforcement or extinction.
